Abstract: The process consists in successively separating increasingly heavy petroleum cuts at the head of a plurality of columns CO1, CO2, CO3 and Cl0 of a first series of columns which feed individually each column of the second series. The column CO7 is a gasoline stabilizing column which feeds an installation for fractionating light petroleum gases. The column CO4 is a gasoline fractionating column. The columns CO5 and CO6 are columns for separating petroleum naphthas from kerosine. The atmospheric residue collected at the bottom of the column Cl0 is processed in the vacuum distillation column Cl2 and the residue from this column is processed in the second vacuum distillation column Cl3 after reheating in a furnace. By carrying out a succession of progressive separations performed in a series of columns of small volume, more efficient utilization of the recovery heat is achieved.

Abstract: ABSTRACT OF THE DISCLOSURE         A light emitting tube and a method for producing such  a  tube  in  which  stable  lamp  characteristics  are assured  by  preventing  an  adhesive  agent  used  in  the manufacture of  the  tube  from being  in contact with the interior of the tube, thereby preventing the reaction of sodium  or  the  like  with  the  adhesive  agent  and  the consequent  reduction  in  the  quantity  of  sodium.    An annular plate is fixed on an outer surface of each of the tube end walls through an adhesive agent.  A part of this adhesive agent fills a gap between the annular plate and the tube end wall, but, due to a capillary action produced by the annular plate,  the end of the adhesive agent  is prevented from entering the inner surface of the tube end wall.

Abstract: ABSTRACT:          Amplifier with rail-to-rail input capability and controlled transconductance.           A differential amplifier operable between a pair of supply voltages that define a rail-to-rail supply range contains a pair of differential portions (20 and 22) that together provide representative signal amplification across the supply range, although neither differential portion individually does so. A current control (24) regulates operating currents (IN and Ip) for the differen-tial portions in such a way that the amplifier transcon-ductance can be controlled in a desired manner as the common-mode part (VCM) of the amplifier input signal (VI+ and VI-) varies across the supply range. The trans-conductance is typically controlled to be largely con-stant. A summing circuit (26) selectively combines inter-nal currents (IA, IB, IC, and ID) from the differential portions to generate at least one output signal (IO+ and IO-) representative of the input signal.

Abstract: Abstract of the Disclosrue In a multidirection multiplex communication system of the demand assign type including a central station and a plurality of subscriber stations cooperating therewith, a maintenance poling signal assigned to a maintenance time slot of a frame is sent from the central station to a subscriber station not requested to send an information signal, the subscriber station inserts a maintenance burst signal in a time slot of a frame corresponding to the maintenance poling signal and sends back the maintenance burst signal.  The central station extracts the timing signal transmitted from the subscriber station out or the maintenance burst signal and compares the extracted timing signal with the reference timing signal in the central station to form a time difference signal.  After inserting the time difference signal in the maintenance frame the central station sends back the time difference signal to the subscriber station.  Based on the time difference signal, the subscriber station controls the transmission timing to be commensurate with the reference timing of the central station.

Abstract: ABSTRACT               CREDIT TRANSACTION ARRANGEMENTS      The invention concerns call-charge payment of telephone calls from payphone telephone instruments (PI) using a credit card, or the like.  The invention provides credit transaction arrangements for automatic call-charge payment of calls established through a telecommunications network from payphone instruments (PI).  The payphone (PI) is provided with a credit card reader (CRM) which when activated causes the payphone (PI) to automatically set-up a path (NAP) through the telecommunications network to credit transaction equipment (CCE) at a remote location (NP) within the network.  Initially, a first record data (HEAD), being relevant to call-charge payment, is transmitted over the path (NAP), validated and stored (CDS) at the credit transaction equipment (CCE), and the path is promptly disconnected.  The subscriber then sets-up a communication path through the network to a desired called subscriber for communication purposes.  Following the release of the communication path, second record data (TAIL), also being relevant to the call-charge payment, is compiled in the payphone and subsequently transmitted to the credit transaction equipment (CCE) and combined with the first record data (HEAD) for call-charging payment purposes.  A data base (DB) employing a computer is concerned with the bill processing.
